What ever the true "reason" for all this is, it certainly seems that it is all an "over the top" military exercise, with "the powers that be" seemingly taking great delight in "showing force" and imposing themselves on people. Seeing pictures accompanying articles about it (yes even if the article is a "move on folks, nothing to see here, so mind you own business" article) I am reminded of movies about invading armies imposing themselves on a town and "showing force". Personally I think that the main thing behind it is to get people used to having soldiers patrolling their streets, shouting orders at them, taking what they want out of the town and BEING OBEYED - that is a big one. High ranking military are used to issuing orders and being obeyed, they want to be obeyed by civilians too. This will be necessary in a martial law situation. I don't believe that the ptb is preparing for a specific martial law situation, but they do realise that eventually it may well come to that and they want to know how to handle it and they also want civilians not to be too surprised if/when they are rounded up, disarmed and ordered to obey.
I think also (this might be a really unpopular view, but I'll live with that) that the US gov't has realised that it has to "take out" certain "dangerous" (dangerous to them) sections of the population. It has started by the police mounting this orchestrated "shootout" in Waco with the motorcycle clubs. So many executions and not a policeman among them ..... pretty amazing.
There can be no other explanation for these military exercises happening on "home turf". If, as has been claimed, the military is merely practicing for an "overseas war", they would be training on military bases or isolated areas not in American towns.
Sure lots of commentators "misinterpret", "misconstrue", "speculate" or are generally totally strapped for answers. In that case why do they not get REASONABLE answers from government or the military?
As for "formal requests from the event organisers to the small towns". Yeah, that turned into kind of a joke, it seems the small towns really didn't have a choice, neither did the private land owners whose property was "commandeered" by the military to "practice" on.
Not too long ago it didn't used to be like this but now when I read of the US gov't, the word "bully" comes to mind.
